Ask HN: React Native Equivalent of NativeScript Playground?

"{N} Playground is a solution that allows you to write your {N} code in a web client at play.nativescript.org and deploy it to your device with the help of the NativeScript Playground app (Android, iOS) and the NativeScript Preview app (Android, iOS)"

^^ does anyone know of a React Native equivalent? I like {N} Playground as you can dump components in, and see them almost immediately on you device using the app - as a newbie (only have working knowledge of HTML/CSS/JS) it's been a cool tool to see how syntax looks/dive right in.

Colleague showed me this today, and I've been wanting to learn React Native for a while, so figured I'd ask - half curious/half serious
